About Blue Ridge Buckbean

Blue Ridge Buckbean, also known as Carolina Lupine or Southern Lupine (Thermopsis villosa), is a striking legume that brings architectural interest and bright color to the early summer garden. This upright perennial produces dense, elongated racemes of buttery yellow, pea-like flowers that can reach heights of 3 to 5 feet. Its attractive trifoliate leaves are a soft bluish-green, providing a lovely contrast to the vivid blooms. Native to the Appalachian region but adaptable to much of the eastern United States, it is often found in open woods and clearings. The flowers are highly attractive to bumblebees and other long-tongued pollinators who can navigate the specialized blossoms. As a nitrogen-fixing legume, it helps improve soil health over time and is remarkably drought-tolerant once established. It thrives in full sun and well-drained soil, making it an excellent low-maintenance choice for the middle or back of a sunny border. Its sturdy stems and long-lasting flowers also make it a wonderful addition to cut flower arrangements.
